Your whole digital life pours through the air on invisible radio waves. This short course explains how: Wi-Fi is radio (the same family as light, just lower frequency), how 1s and 0s get encoded onto a wave (modulation), why 2.4 GHz reaches farther while 5 GHz is faster, and why a network full of busy devices slows to a crawl because everyone is sharing the same airtime.
